Delays are expected on state roads 112, 826, 836 and Florida’s Turnpike, as well as on Milam Dairy Road.

On 826, the Palmetto Expressway, all northbound lanes will be closed from south of West Flagler Street to 836 between 11 p.m. Friday and 5 a.m. Saturday. The ramp from West Flagler to northbound 826 also will be closed between 10 p.m. Friday and 5 a.m. Saturday. The shutdown will allow the contractor to work on a bridge over the roadway.

On the Homestead Extension of Florida’s Turnpike, lane and ramp closures will continue as part of the construction of express lanes. As a result, the turnpike will be widened to eight and 12 lanes, and the State Road 874 interchange will be realigned. Construction began in March 2014 and is scheduled to be completed in early 2017 at an approximate cost of $145.3 million.

Meanwhile, the Florida Department of Transportation plans to begin roadwork along Northwest 72nd Avenue/Milam Dairy Road at 74th Street in Hialeah and Medley. The project, which is expected to take three months to complete and cost $199,000, includes reconstruction of sidewalks, curbs and gutters, and repaving.
